I'm intending to compare TAC and exterminator and pos 17, to H4350, just to see.
My limited work with Reloder 17 was unsatisfactory in 7x57 and 140s. But I did not push much passed a educated guess starting load and never got back to it. In my other guns 17 worked better as it reached max. pressure and fuller loading density. I do wanna go back and restart testing it. But am trying to get rid of other components that have worked in the past
